Male mosquito head, light micrograph
Male mosquito (family Culicidae) head, light micrograph. The mosquito's head is dominated by its large compound eyes (black spheres). Sprouting from the head are long, plumose (feather-like) antennae, which are sensory organs covered in fine hairs. Males have more elaborate antennae, which allow them to locate females for mating. The long thin proboscis protruding from the head is used for feeding. Only female mosquitoes feed on blood, males feed on plant liquids. Magnification: x40 when printed at 10 centimetres wide.
